The former Arsenal man has sung the praises of Aaron Cresswell.
The Reds' loss, then, appears to be very much Sam Allardyce's gain, with Keown singing Cresswell's praises, as well as complimenting Arsenal loanee Carl Jenkinson.
"Carl Jenkinson has the potential to be a top player and Aaron Cresswell is a shining example to any young English professional," Keown wrote in his weekly column for the Daily Mail.
"Released by Liverpool at youth level, he kept going, worked his way up via Tranmere and Ipswich and is now carving out a career at the top level."
